Description

solar water heaters

Technical field:

The utility model relates to the technology of a solar water heater, which is an improvement on the overall structure of the solar water heater, in particular a solar water heater.

Background technique:

Solar water heaters are becoming more and more popular because of their advantages in energy saving, environmental protection, and convenient installation and use. Especially the residential users on or near the top floor are more and more generally installing and using solar water heaters. But existing solar water heater, its basic structure does not have too big change in the past, still mainly adopts that heat collector is installed on the support, and the structural form of cylindrical water tank is installed on the top of heat collector again. This existing solar water heater is not only bulky, inconvenient to install and use, but also slow to exchange heat and cold, easy to generate scale, low thermal efficiency, and difficult to meet the needs of users.

Invention content:

The purpose of the utility model is to provide a solar water heater which speeds up the cold and heat exchange, prevents scale formation, has high product quality, high thermal efficiency, energy saving, and is easy to install and use.

The technical solution of the utility model is: a solar water heater with a heat collector. The circulation branch pipes in the heater are connected, the circulation main pipe is connected with the low-temperature water inlet pipe, and the tubular water tank is connected with the high-temperature water outlet pipe.

The heat collector installed on the tubular water tank described in the utility model is installed on one side or two sides thereof. The heat collecting tubes of the heat collector installed on the tubular water tank have double rows or single rows. The tubular water tank is wrapped with an insulation layer.

The utility model has the beneficial effects of novel design, accelerated cold and heat exchange, prevention of scale formation, high product quality, high thermal efficiency, and energy saving. Lightweight structure, easy installation and use, especially suitable for installation on balconies and other places.

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Description of drawings:

Accompanying drawing is the structure diagram of a kind of solar water heater of the utility model.

Detailed ways:

Accompanying drawing has described an embodiment of the present utility model, and in this example, heat collector 1 is arranged, and one end of heat collector 1 is connected with tubular water tank 2, and circulating main pipe 3 is housed in tubular water tank 2, and circulating main pipe 3 is connected with the circulation branch pipe 4 installed in the heat collector 1, the circulation main pipe 3 is connected with the low-temperature water inlet pipe 5, and the tubular water tank 2 is connected with a high-temperature water outlet pipe 6. The heat collector 1 that is installed on the tubular water tank 2 is installed on one side or two sides thereof. The heat collecting pipes of the heat collector 1 installed on the tubular water tank 2 have double or single rows. The tubular water tank 2 is wrapped with an insulating layer 7 .

The water heater of the utility model can rapidly heat the hot water in the vacuum heat collecting tube within a limited illumination time, and greatly increase the water temperature of the water heater in a short time.

When the hot water faucet is turned on, the tap water enters the diversion circulation main pipe. Under the action of pressure, because the pressure of the diversion circulation main pipe is greater than the pressure of the diversion circulation branch pipe, the water enters the circulation branch pipe inserted into the vacuum heat collector, and because the diversion circulation branch pressure is greater than that of the connected pipe type. The pressure of the water in the water tank pushes the high-temperature water in the vacuum heat collecting tube to the connected tubular water tank, and pushes the hot water to the water outlet at each split preheating port.
